This is the largest of our species in ex])anse of wings, though not so 

 robust as male B. viade/'actalis, and seems to he con lined to a uorthern 

 range, none of my si)ecimeiis being from any h^cality much south of 

 Albany, Avhil(i it seems to be scarcely common anywhere. Mr. Grote, 

 in stating the differences between his B. lentiffinosa and />'. rcllifera, 

 very fully detailed the difl'erences between the sexes, for such is the 

 relation these species bear to each other. The male {hntiginosa) is 

 larger, somewhat more robust, and the colors are dull, the contrast 

 little marked. 



The si)ecies is i)eculiar by the livulous, brown, transverse strig;e, and 

 by the long, straight i>alpi, which scarcely differ in the sexes. The 

 apices of the jniniaries are more than usually i»ointed, and the outer 

 margin is unusually excavated below that jiomt. In all these (charac- 

 ters, but especially in the tirst meiitioiied, the species is like Ilypena 

 rather than BomoIocJia^ and is an intermediate ty]»e. If others are 

 found fully agreeing with it JMr. Grote's genus Me(/hi/pena may again 

 come to be used.

Ground color rather pale chocolate brown, varying in shade. Head 

 and thorax concolorous. Abdomen more fuscous or smoky ; concolorous 

 with the secondaries, rriinaries with a somewhat .oblique, irregular 

 l)atch in the median space darker brown, and an oblique shade from 

 apex extending inward to the transverse posterior line at about the 

 median vein. Basal space the lightest i)ortion of the wing. Trans- 

 verse anterior line browMi, slender, not prominent, forming a long out- 

 ward angle in the submedian interspa(;e. An oblique line of raised 

 black scales runs nearly parallel and only a little within this line, .so far 

 as it extends outwardly, but continues in the same cour.se to the inter- 

 nal vein, where it joins the ])ale, luommcnt line. Between this black 

 line and the median line the dark central portion ot the wing is IxmiikUmI. 

 Median line pale, dark margined inwardly, outwardly obli<iu(' to vein 3, 

 with a small angle on the cell, then inwaidly obIi(|ue, with little incurves 

 in the inters])aces. Beyond this line a bluish gray .shade suffuses the 

 space to the .subteiniinal line, cut oidy by the oblKpie dark shade from 

 below apex. Transver.se posterior line dusky, followed by a paler-shade 

 line, even oi feebly lunulated, somewhat dilated on thecosta, in general
